Objects the improvements are the production of a vapor burning device of relatively simple, convenient 1 and durable construction and'eflicient Operation adapted to 6 be used for the heating of living apartments and also for various other purposes, in which the tank for liquid fuel, pressure generating means therefor, vaporizer, manifold and burners are so constructed and arranged that 10 they form a composite unit which may be easlly inserted in and removed from a stove frame and may be employed'in connection with various external frames or'housings'or Without such casings and with or Without other means for supporting cooking or heating vessels or otherwise applying or distr'ibuting the heat of the burners. d

Other objects and advantages w1llappear from the following drawingsand the follow- 50 mg description. r

In the said drawings,Figure 1 'i's'a front view of an indoor'heatingstove casing with the unit comprising tank, vaporizer, man fold and burners, pressure-device and their accessories mountedtherein, embodying the im 'ro'vei nents;

li ig. 2 is a View ofthe right hand end thereof; I

Fig. 3 is a front elevation of the said unlt removed from the stove casing; and

Fig. 1 is a plan thereof. r The stove frame or casing comprises-top 1, sides 2and 3-, back 4,1ower front plate 5, inwardly curved front deflector plate 6 hinged to the plate 5 at 7, inwardly inclined mner sides 8 and 9 and bottom end bars 10 rigidly connected with feet 10a and with supporting bars 106 running across the open bottom of the frame from end to end. Suitable cold handles 2a and 3a are hinged near the top of the sides 2, 3, for lifting and carryingthe drum casingand'tray, and grids 11 of refractory inaterial-in this case four in num ber-are mounted withinthe drum above the deflector plate and back of the rear upper edge thereof to receive the combustion from the burners andproduce a heat-radiating glowing member or front; The details of A construction and arrangement of these parts are not essential features of the present improvements. The hinged inwardly and upwardly curved deflector plate 6, however, is a feature, and is adapted to be turned outwardly and downwardly to open the drum and give access tothe burners and other'parts therein for lightin'gor other purposes. In normal position it is supported by curved bosses 12 in the sides 9, and the grids 11 are supported by an open shelf 13 extending across the Steve at the inner edge of said deflector; 1 l r The fuel supply and combustion -unit=comprises a tank 14, burners 15, vaporizing tube 16,- vaporizing burners 17, manifold 18',pressure pump 19, supporting head 20, and connections; These partsare all rigidly connected to form a complete unit whichmay be placed in a stove casing or otherframe or removedtherefrom, as a unit, transported and handled or used in various ways; The tank 14 is connected with the supporting head 20 by means of a strap orband 21; secjuredaround one endand brackets22 fixed to said-bandand to the head. It is also con nected to the said head by means of the drip pan-23 which is mounted thereon by means of supports 25 and 26, extending outwardly from the band 21 and fromthe band 24 at the opposite end of the tank and havinglaterallyextending arms 27 and 28, the extremities of which are turned over and grasp the side edges of said pan, the pan having a downwardly turned end 29 secured to the said supporting head. 1 i

- The member comprising the vaporizing tube, manifold, burners, and vaporizing burners consists of a hollow tubular casting 3.0 with a long'tubular member 31 on which the hollow burners 15 are formed and a shortor member '32 of the manifold 18, a branch tube 33 communicating with'31 to supplyvaporized fuelto the vaporizer heating burners 17 thereon and the vaporizer tube 16 extending throughthe supporting head 20 and having its opposite reduced end 3 1 extend ing through and fixed in the laterally extending circular' head and shield 35. The said casting. has feet 36 at one end and 37 at the opposite end secured to the" drip pan, so that the unit just "described is rigidly mounted thereby on the tank and rigidly connected with the supporting head. A central filling hole is provided in the tank and this hole is securely closed by means of a cap 39.

*uel from the tank passes through the T connection 40, the fuel tube 41 and the union 42 to the vaporizing tube 16 and thence through the manifold 18 to the main burners, a needle valve 43 controlled by the handle 44 regulating the passage of vaporized fuel into the manifold or shutting it off altogether, an adjustable shutter 45 on the manifold being provided to regulate the admission of air thereto through the air intake port 46. Fuel to supply the vaporizer heating burners 17, for initial heating, passes through the connection 40, the pipe t? controlling valve 18, operated by the wheel 49 and through the pipe 47a. During the normal operation of the main burners, however, the vaporizing burner receives its fuel through the branch pipe 33, the valve 18 being closed, and in this manner the heating of the vaporizer tube is automatically regulated to meet the needs of the burner, since the volume of vaporized fuel supplied to the vaporizer heater depends. upon the amount of such fuel admitted to the main burners and the combustion of the said heater is therefore increased and reduced with the combustion of the main burners.

All burners are preferably provided with plugs 38 having numerous orifices therein for the passage of fuel.

Air pressure is communicated from the pump 19 to the tank 14 through pipe 50 having a valve 51 thereon controlled by the wheel 52, and the pipe 50a to the connection 40, and the pressure in the tank is indicated by the gage 53 communicating with the main fuel conduit 41 at the union 42.

In the present case, the end of the tank op-' posite the supporting head is provided with legs 54 on which it may be supported when in upright or filling position, the end of the drip pan 23 acting as the third leg when the tank is in this position. These legs also serve in the illustrated application to space the unit from the inner end of the stove casing.

V In the operation of the device the tank is first filled and placed under pressure by means of the pump, liquid fuel is then ad mitted to the vaporizer heater to heat the fuel in the vaporizer, the heater is then lighted and fuelthen admitted from the vaporizer to the manifold by means of the needle valve and the main burners lighted. When main burners are in operation the liquid fuel to the vaporizer heater is then shut off, and the said heater supplied with fuel from the main burner tube. Combustion is regulated throughout the operation of the stove by means of the needle valve. v i f In the illustrated application of the improvements the unit, including tank vaporizer, manifold and burners is passed into the stove casing and supported therein by the bottom members 10, 10b, and may be readily removed therefrom for filling. This particular arrangement, however, is not essential, and the stove casing may be constructed and arranged to be lifted off the fuel and combustion unit or the fuel and combustion unit may be permanently mounted in the bottom of the casing and the upper part of the casing made removable. Other constructions and arrangements for housing the unit may also be employed. As before noted, the tank and burner unit may be used in various ways, and may be made in various sizes and shapes and with any desired number of burners. Thus it may be passed under an ordinary grate for the purpose of heating or cooking food or other substance in any ordinary way. The unit is in effect a portable stove and may be used indoors or out for all cooking and heating purposes. The unit may also, if desired, be provided with a base of its own and with cooking grids or other supports, for utensils or containers to be heated, mounted upon said base or upon the ground. It will also be apparent that various changes in the construction and arrangement of the parts herein shown and described may be made without departing from the scope of the improve ments.

In the illustrated embodiment of the improvements the burners are located below the grid of refractory material and are spaced a shortv distance therefrom and the hinged deflector plate protects the burners from drafts and directs currents of air passingup from the open bottom of the stove to said burners and through said grid along with the burning gases of the burner combustion so that a large volume of heated air passes from the upper party of the stove and heat is also radiated from the grid. The supporting base of the fuel and combustion unit serves to close the end of the stove when the said unit is inserted therein, as well as to unite the elements of said unit and maintain them in their proper positions and relations at all times. There is thus provided a heating stove of efficient and convenient form and compact and attractive appearance.
